hi,

i'm currently using multibit as my bitcoin wallet and i have several different computers.  i have it installed on my work computer, then i backed up my wallet and imported it to my home computer but it doesnt seem to sync with each other.  so my wallet at my work computer has a couple more transactions than the one i have at home.  are they supposed to sync with each other? 

2nd question is about my wallet for namecoins.  i did some command line and got my namecoin address but thats all i have.  so if i lose that address, i loose all my namecoins?
